PROGRAMME-crock.

SFECIFICATION forming part of Letters Patent No. 292,456, dated January22, 1884;,

Application filed Xovembcr 30, 1883. X0 model.)

I0 (6 whom, it may concern.-

Be it known that I, THEODORE XVILMER, a citizen of the United States,residing at Millhousen, in the county of Decatur and State of Indiana,have invented new and useful 11nprovements in Programme-Clocks, of whichthe following is a specification.

My invention has forits object to produce a programme-clock which willnot only strike the hour or time for the ending of one and conr meneentof another exercise or recitation, but will also show at a glance thedifferent recitations for one or more days, the time to be devoted toeach recitation, and the order in which they follow each other, so thatmore than a limited time will not be unintentionally devoted to onerecitation, and so that the recitation to follow next in order beingknown, preparation therefor may be made; and to the accomplishment ofthose ends the invention consists in a dial-plate or map made intodivisions or sections corresponding in number to the days or school-daysof a week, marked on a movable hand or pointer, which may be the hour orminute hand of a clock or alarm mechanism, the said sections ordivisions being adapted to be marked with the recitations for a givenday, and eachin extent being such that when the allotted time for aparticular recitation has elapsed the hand or pointer will have traveledthe distance representing the time assigned to that recitation.

A detailed description of means for carrying out my invention'willbehereinafter given.

The accompanying drawing represents a front elevation of a clock, suchas the Estell programme-clock, with my dial-plate or map appliedthereto.

The alarm or clock mechanism may be of any approved construction forstriking an alarm at stated intervals in accordance with a predeterminedprogrammesuch, forinstance, as what is known as the Estell programmeclock or regulator, for which patents were granted to S. F. Estell,January 11, 1870, No. 98,678,

and October 10, 1871, No. 119,833. To the face A of such a clock I affixa dial or map plate, A, made of sheet metal or other suitable material,having a central circular opening, B, to expose the dial-plate of theclock, and having its face preferably colored black,

made with a surface from which marks may be erased, and divided into aseries of divisions, 0, by a series of circular lines, D, and into aseries of colnmnsbya series of lines, E, radiating from the center ofthe dial-plate or map toward its periphery. In the drawing there arerepresented a suiticient number of circular lines to form five concentric divisions, one for each schoolday of the week, but any number ofsuch divisions desired may be formed. These divisions aremarked,respectively, with the days of the week,beginning with the outerdivision, which is marked Monday, 7 and continuing on down to the innerone, ending with Friday. The radiating col umns, orso many of them asare necessary, are marked with the lessons for the day. For in stance,take the outer concentric division, which is Monday. It is marked sothat in one column there will appear the first recitatation for the day,Reading, inthe next section the following recitation, Arithme tie, inthe next the recitation to follow the last, Penmanship, thenin the nevt,Grainmar; and, finally, Spelling. The above recitations are supposed toconstitute all that there will be before the noon recess, and above eachrecitation is marked in figures the time allotted to eachforillustration, thirty min utes for composition, and twenty minutes forpenmanship. Then follows a blank space, in which will be marked the timeallotted for recessfor illustration, one hour. and beneath that Free.Then follow the sections marked with the recitations for the afternoon,with the hour allotted to each, marked in the manner already described,-and next there may follow blank spaces, in which can be marked the hourfor opening or closing, orsuch announcements as may be desired to bemade. The concentric division next below the outer one will be marked inthe respective columns with the recitations for the day which thatdivision represents, and so on down the several divisions.

The recitations for the several days may be marked in different colors,so as to readily distinguish one from the other, and the marking may. bedone with chalk or other substance that can be easily rubbed off, sothat the programme of studies and their order may be changed as desired.At the lower or inner end of each section marked with a recitation theremay be marked the initial letter of the recitation at the head of thesection or column, or with whatever other exercises that may be desired,so as to indicate on the last schoolday of the week the lesson orrecitation for the first day of the next week.

The hand or pointer of the clock will be extended to the outer divisionof the dial or chart plate, and will be divided into divisions markedand numbered correspondingly with those of the days of the week on thedial or chart plate. This movable hand or pointer is moved by the clockmechanism, and the alarm is set in the way usual in the programmec-lockshereinbefore referred to, so that thelength of timerequired forthe handor pointer to pass from one section or column to the next will be thetime alloted to the recitation marked in that column, and the alarmsounded when that period of time has elapsed.

The concentriclines and radiating lines will, by preference, beindelibly marked on the face of the dial or chart.

, It will be seen from the foregoing description that I provide a clockwhich will indicate the hours of the day, the recitations for one ormore days, the order in which they occur, the time allotted to each, andwhich will sound an alarm at the ending of the time allotted to onerecitation and for the beginning of the next recitation.

The device is simple and cheap of producti on, and can be attached toprogramme-clocks already in use at a comparatively small expense.

Having thus described my invention, what I claim is- 1. The combinationof a dial plate or chart divided into a series of columns, and a seriesof concentric divisions adapted to be marked with one or more days ofthe week, with the recitations for one or more days in their sequence,and with the time alloted for each, a pointer marked with the days ofthe week corresponding to those that may be marked on the dial-chart,and any suitable mechanism for moving the pointer over the dial-plate,

so as to pass it from one column to the other,

to indicate when the time for one recitation has ended and that for thenext arrived, substantially as described.

2. The combination, with a clock to indicate the hours of the day, of adial chart or plate divided into a series of columns and a series ofconcentric divisions, adapted to be marked with one or more days intheir sequence, and with the time allotted for each, a pointer markedwiththe days of the week corresponding to those that may be marked onthe dialchart. and mechanism for moving the hour-indicating hands of"the clock to indicate the hour of the day, and in unison therewith thepointer over the dial-plate. so as to pass it from one column to theother, to indicate when the time for one recitation is ended and thatfor the next arrived, substantially as described.

In testimony whereof I h ave hereunto set my hand in the presence of twosubscribing witnesses.

THEODORE VILMER.
